Altitude Sickness and Acclimatization


Altitude Sickness and Acclimatization


Altitude Sickness and Acclimatization - Acclimatization is the process in which an individual organism adjusts to a change in its environment  (such as a change in altitude, temperature, humidity, etc. that allows it to maintain performance across a range of environmental conditions.

Altitude Sickness and Acclimatization

An altitude and acclimatization is the most important thing for high altitude travel or trekking. While you go higher, the oxygen level is getting thinner. When you cross around 2000 m above the sea level, saturation of oxyhemoglobin levels starts to decrease rapidly in the blood. So that's why you have to be careful while you are going on high altitude travel and you should follow the altitude and acclimatization rules.

Altitude Sickness and Acclimatization


  • Headache 
  • Dizziness
  • Nausea
  • Vomiting 
  • Fatigue and loss of energy 
  • Shortness of breath
  • Problems with sleep
  • Loss of appetite 
  • Feeling uncomfortable

How to Avoid Altitude Sickness?

  •  Climb  altitude gradually 
  •  Drinks lots of liquid while trekking
  • Avoid alcohol, smoking, and sleeping tablets 
  •  Don’t go trekking on the mountain alone 
  •  Don’t go higher if you get the symptoms of altitude sickness 
  •  Descend immediately if symptoms get worse
  • Don't leave alone to the person who got altitude sickness
  •  Dress warmly while you are trekking
  • Use preventive medicine while trekking

Embarking on the awe-inspiring Himalayas in Nepal entails not only breathtaking landscapes and cultural richness but also demands careful consideration of altitude-related risks.

Two formidable threats, High Altitude Pulmonary Edema (HAPE) and High-Altitude Cerebral Edema (HACE), loom at higher altitudes, requiring trekkers to be well-prepared for a safe and rewarding journey.

Understanding the Altitude Sickness Types is paramount.

HAPE, characterized by fluid accumulation in the lungs, and HACE, the swelling of the brain due to fluid leakage, can be life-threatening. Recognizing symptoms early on is vital for prompt intervention.

Preparation becomes the linchpin for a successful trek in Nepal.

Prioritize physical fitness through a consistent exercise routine, plan a gradual ascent with rest days, stay hydrated, and consult healthcare providers about the judicious use of Acetazolamide (Consultation Required) for altitudes exceeding 3,000 meters.

Trekking Practices specific to the Nepali Himalayas are crucial. Ensure proper rest for recovery and altitude adaptation, maintain a balanced diet rich in carbohydrates, dress in layers to ward off hypothermia, ascend gradually to avoid altitude sickness, and carry emergency communication devices for unforeseen situations.

By adhering to these guidelines, trekkers can significantly minimize the risk of HAPE and HACE, ensuring a safe and unforgettable expedition through the stunning landscapes of the Himalayas.
